Abstract
A well developed approach to the study of complicated systems (proteins, liquid crystals, membranes) is based on the use of probes, either molecules or stable free radicals, which, dissolved in the system under investigation, report on the structure and dynamics of the complex system. In liquid crystals the order and dynamics of the probe, revealed by a suitable spectroscopic technique, can be used to investigate the mesophases under various conditions, including phase changes and biphasic regions. For lyotropic systems the solvent itself can be used as a probe of the behaviour of the aggregates. We should be aware, however, that the probe can disturb the mesophase or vice versa that the solvent can more or less deform the dissolved molecular probe. Moreover the anisotropic potential acting on a dissolved molecule is a solute-solvent property of the solution and therefore can provide the possibility of gaining valuable insight into the mechanism governing solute-solvent interactions.
